Purified histones are bound to the wells of a polystyrene microwell plate under conditions that will preserve the antigen in its native state. Prediluted controls and diluted patient sera are added to separate wells. After washing, an anti-human IgG conjugated to horseradish peroxidase is added. After incubation and washing, tetramethylbenzidine (TMB) substrate is added to enable visualization of antibodies. The enzyme reaction is stopped and color development measured at 450 nm in a microtiter plate spectrophotometer.(Package insert: QUANTA Lite. Histone ELISA 708520, INOVA Diagnostics, Inc.)
